I’m sure there are ways to make it more convenient to use a terminal with dyslexia but I’m gonna guess that it’s always going to be a bit of an uphill battle. It might make more sense to use a gui in that case for many applications. Conversly, it’s also good to make sure you have a proper terminal interface as well for disability reasons, but also for the convenience that a terminal interface can provide for people who are familiar with the terminal.
